I don't have a gun, never really needed one the last 43 years.
I think you're pretty safe camping in most of the places you might camp. I don't think you would want to camp out in Compton, or New York City, South Side of Chicago, or Detroit, or... THEN you might need a gun.
I wouldn't worry about that Deliverance movie thing too ?much though. Unless you start to hear dueling Banjos. :laugh:
